lost my best friend/sister

I lost my best friend of 37 years last week to pancreatic cancer. She was the most beautiful person inside and out. She would help anyone in need. I feel most sad for her little boy, who's only 6. She was diagnosed 18 months ago, so I've had a little time to process this. Today tho, today it hit me hard! At times, at work, it was hard to keep it together. I miss that lady! I have a big family. I'm not particularly close with any of my siblings. I love them all though. She was more like another sister to me. I'm rambling, I know. This sucks! I thought we might grow older together. We had hopes and dreams. She was my only real friend. I have acquaintances, but no real friends. No one that I can call and go to dinner with or grab a drink after work. That type of thing. I'm not a shut in, I go to the gym and am friendly with people there. I know I'll get through this somehow. I've done it before when I lost my baby ( a full term stillborn). Thanks for letting me clear my head a little bit.
